I put the feeders up to invite the songbirds, Mr Blue Jay. I'm not sure if anyone's told you, but your song sucks and you eat too much.

Sure are nice to look at though....

This is a feather I found today of a dusky crag martin (I know this because I watched it get shed by one) and just wanted to talk on something cool about feathers in general and how they can be used to know more about the state of the bird that they came from.

Growth bars are faint lines and barrings which form over the normal growth of feather growth, typically forming every 24 hours as the feather grows, these bars show light bands and dark bands. The dark bars are from feather materials created during the day and the light bars during the night. And each light and dark bar corresponds to a 24 hour period of growth, so scientists can actually use growth bars to calculate how much time is needed to replace all of the feathers on a bird's body in some pretty useful ways. For instance, when all the growth bars on all feathers of a bird seem to be in line pretty uniformly, that usually means that all the feathers were replaced at the same time, which usually only happens during the first set of plumage (which means that the bird is still pretty young even if it sports adult plumage) so you can also also get clues about how old the bird may be from its growth bars.

But age and growth arent the only things you can get from looking at these growth bars, but also the birds overall state of heath. The growth bands being regular means that the bird was living good and that availability of the diet wasnt really an issue for it. But on the other hand a bird going through tough times will have irregular growth bars as well the apperance of fault bars on their feathers.

When a bird is subject to stressors such as a period of poor nutrition from a lack of sufficient food resources, illness, psychological stressors or due to sudden muscle contractions in the feather follicle (like a fright molt to distract and escape predators) its body diverts the protein, energy, and micronutrients required for synthesising keratin and developing feathers properly towards its vital systems and organs instead leading to the feather barbules not developing right and instead appearing as narrow transluscent bars of missing barbules in the feathers. These "defects" in the feather called fault bars and can prove helpful in understanding the life history of the certain bird that they came from.

We’re having a sticky beak into the wild and wonderful world of the magpie’s lesser-known relatives: currawongs and butcherbirds. Don’t let their unassuming looks fool you. These birds have big personalities, even bigger voices, and a knack for being both vicious and sweet, often in the same breath. From haunting melodies to interesting table manners, we’re diving into what makes these Aussie songbirds so amusing and just a little bit f*cked.

A turkey in a tree! This guy was settling in for the night as I came along with my camera

Birds adapt their sounds based on habitat, latitude, and size, with smaller birds using wide frequency ranges to ensure survival.

Blue Jays are year-round around here, but they really feel like a winter bird to me.

Bonus, Come on let me see you shake a tail feather

We only go this way 2-4 times a week. The next couple of visits nothing happened and I just assumed it was a fluke. But then!

I did the usual daft noise and left treats on Christopher Cragg’s gravestone. 2 of them came! As me and Dolly got about 10 metres / 30ft away they plopped onto the grass and then one of them jumped up, ate one treat, put the other in its beak and flew off to eat it in peace.

Since then every time I visit so maybe 10 or 15 times, they’ve appeared! Sometimes before I put the treats down, sometimes after.
Occasionally they’ll follow us around the cemetery whilst Dolly hunts for cat scent

I love all birds but Crows and corvids in general have a special place in my heart

i rescued a green cheek conure going on a decade now. a friend to sit with me while I worked. my first bird, my kids grew up with her.

i write this from the vet who has just put her down. she was far older than we expected and was sick for the first time... the last time.. this week.

hug your bird.

As I pass through the cemetery on my dog walk there’s a couple of crows who often hang around in a certain corner.
In an attempt to befriend them, for the past year or so I’ve been making loud sort of crow noises and leaving a dog treat or two on the top of the same gravestone in the hope of them associating the strange human skwawks with a gift. A few days ago I nearly gave up bothering as it’d never worked but didn’t want to risk it

The crows were not around as is fairly common.
I put a couple of treaty crumbs in the usual spot and when I was about 20 metres further on I checked back and there it was, a gorgeous beautiful crow

Yesterday was the same. No sign of the crows, skwawk, leave treat, skwawk, give Dolly a treat cos she’s cottoned onto it by now. Check back and there’s the splendid beastie again!

I was buzzing all the way home. I’m going to go again soon

When awake, Zebra Finches sing a well-regulated line of staccato notes. But their sleeping song movements are fragmented, disjointed and sporadic—“rather like a dream,” Mindlin says. A dozing finch seems to silently practice a few “notes” and then add another, producing a pattern of muscle activity that reminds Mindlin “of learning a musical instrument.”

Hey, little buddy!

I heard this little guy chirping in a bush while I was cleaning up some dog poop. He didn't flinch when I reached in with my camera to get this shot, so I reached in again and petted him gently with my finger. Hopefully, mom or dad will come back with some food soon.

TL;DW: Some songbirds incorporate cigarette butts into their nests as pest control.

This osprey had just brought a fish to its young in their nest on top of this man-made osprey platform.

Found a guy.

His name is Buddy. It's crazy how much a bird can cheer me up even when was feeling good in the first place! Apparently, he just likes to meet people, so the owner just brings him out to do so every now and then.
